In order to find out the different types of gametes produced by a pea plant having the genotype AaBb, it should be crossed to a plant with the genotype

Options

A. aaBB
B. AaBb
C. AABB
D. aabb

Explanation

To determine the different types of gametes produced by a pea plant with the genotype AaBb, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Genotype**: The genotype AaBb indicates that the plant is heterozygous for both traits (A and B). This means it has one dominant allele (A or B) and one recessive allele (a or b) for each trait.

2. **Identify Gametes**: To find out the types of gametes produced by the AaBb plant, we need to consider the combinations of alleles that can be passed on to the gametes. Each gamete will receive one allele from each gene.

3. **Use the FOIL Method**: The FOIL (First, Outside, Inside, Last) method can be used to determine the combinations of alleles:
- **First**: A from A and b from B → Ab
- **Outside**: A from A and b from b → Ab
- **Inside**: a from A and B from B → aB
- **Last**: a from A and b from b → ab

4. **List the Gametes**: From the combinations, the possible gametes produced by the AaBb genotype are:
- AB
- Ab
- aB
- ab

5. **Perform a Test Cross**: To determine the unknown genotype, the AaBb plant should be crossed with a homozygous recessive plant (aabb). This will help identify the offspring's genotypes and phenotypes, revealing the gametes produced by the AaBb plant.

6. **Identify the Correct Cross**: The correct genotype for the plant to cross with is aabb, which is homozygous recessive for both traits.

### Final Answer:
The pea plant with the genotype AaBb should be crossed with a plant having the genotype aabb to find out the different types of gametes produced.
